sheets, or of plate glass, and concerns specially the conveying of suchstrips, sheets or plates at the exit from the glass-making apparatus.

The glass is generally "conveyed at-this point by a'system ofmechanically driven rollers which are preferably made all with the samediameter and driven at the same speed, in order to simplify theirconstruction and drive.

Since the diameter of'the conveying rollers 'is rather large, acomparatively large from the glass-making apparatus where the glass-isstill-onlysomewhat (pglastic.

. 'At this'point, the front e e of the strip, sheet or plate producedhas a tendency to deflect, at least in the space between'th'e first twoconveying rollers, and thoughthe glass so may engage on the secondroller,--it is often only with difliculty and after striking against thesaid roller. Striking against the roller causes a blow and 'said blowupsets the edge of the glass,

interfering with the start of the conveying operation. v

When the glass is being madelin a -cont1nuous strip or sheet, the aboveinconvenience 0 may be of minor importance, but in the discontinuousprocesses, in which each sheet or plate is formed by pouring thecontents of a pot of mol ten glass, the difiiculties of starting theconveying operation are re- 5 peated for each successive sheet or plate.

The invention has for object to overcome this disadvantage.

It consists mainly in substituting a positive or automatic start fdr thenatural start of the conveying operation, at the exit from thelass-making ap' aratus, by receiving the lead ng end of the s eet onarigid member, supported by the first few or at least the first twoconveyor rollers, so that correct en gagement on the latter will alwaysbe insured whatever may be the consistency of the leading edge of thestrip, sheet or plate at the exit from the glass-making appa ,plate, thesaid fbait being designed so as to obtain a strong adherence of the endof the strip, sheet or plate in orderto prevent any possibleseparation.- 1 I The invention further consists in constructing thesystem of conveying rollers sothat the ,bait can be kept stationary whenwaiting to receive the end of the strip, sheet .or plate, and be movedin translation as soon as the said end is received.

' In order that the invention may be clearly understood, it will now bedescribed as applied to [conveying strips, sheets or plates made by.rolling, reference being made to a a set.of conveyingrollers and a bait,in "the waiting position to receive the strip,

sheet or plate.

.Fig. 2 is a plan of the arrangement shown in Fig.1.

Fi 3 is an enlarged detail section of a bait -Fig. 4: is a view similarto Fig. 1 of an alternative.

As stated and as illustrated, assuming that 1- and 2 designate tworolling cylinders adapted to form a strip, sheet or plate of glass, that3 designates a receiving table, conducting thejstrip, sheet or plate tothe conve ing rollersfl, 5,6, '7, when the leading e ge of the strip,sheet or plate reaches the space between the rollers 4 and 5, it willhave a tendency to bend on account of its lack of consistency and ofthetendency of the glass to adhere to the. cold roller 4. As a result, theleadingedge will not engage, or engage onlylwith difiiculty, on theroller 5 and'the subsequent rollers.

' a In order to positively insure such engage ment, there is provided'atransporting.ba1t- 8 designed for receiving the leading end of thestrip, sheet or plate and previously located so as as toibear on atleast the first .two'rollei's sand 5.

Conveniently, the drive for a number of g rollers, including thefirst-two rollers on which the bait rests comprises a clutch memberenabling said rollers'to be held stationary while waiting to receive thestrip, sheet'or plate. I

As soon as the said strip, sheet or plate is received, the clutch isoperated so as to drive the said rollers.

The bait -8 may have n merous difierent forms, 'but is conveniently madeas illus trated in'Figs. 2 and 3,,i. e., be provided with a set ofparallel spaced straps 9 connected together at their front part bytwo'or more cross ieces 10, the en'd'crosspiece being an angle ar.

The bait 8 could be extended lengthwise as far as desired under theinclined table following the rolling cylinders to insure great securityin the engagement. The roll- .the bait will in such case For the purposeof. increasing the adheren'ce between the leading ,edgeof the bait, soas to avoid any possible' separation, the straps 9 are preferablytransversely grooved or serrated on .a part of their length,-as shown at11 in Fig. 3.
